Mechanism constructed in. accordance with the invent-ion Will includemeans for dividing the sheet, so that it may be delivered in parts. Inthe particular construction shown, it comprises a slitter 32 mounted onan arm 38 carried on a shaft 34 extending across the machine. Theslitlter is located over and'coperates with the abutment roll 2,

Constructions embodying the invention will include means for forwardingthe sheet, said means acting on each side of the cut formed by thedividing means and coperating with the means which hold the originaledges ot the sheet in forwarding the same. lll-'bile these means may bevaried, and While the operating means may be varied, in the particularconstruction shown, a b aket' is provided which serves to support one.end ot a shaft 36 having a sprocket Wheel 37. The bracket 31 is providedWith an extension 38 which serves, through a suitable stud. to support acoperating sprocket ivheel B'Q A flexible gripper carrying chain 40 runs(iv r the sprocket Wheels 37, 39, the Wheel 37 being the driving Wheel.The 'chain 40 (see Figs. 1, et, and 11) is provided With tivo blocks 41each of which has a horizontal extension 42 which` serves as one jaw ofa gripper mechanism. The corresponding jaw -13 of each gripper iscarried on a rock-arm ,44. These arms 44 are pirated on studsLl-vextending from the blocks 4l. The grippers are normally held closedby springs jl-(i and are opened to seize the sheets by cams i7 fixedinside the arms of the brackets 35. The arms 44 carry rolls 48 whichcontact With these cams. The grippers are opened. to' release the sheetsby cams L19 secured to a chain guide 50, this chain guide beingsupported at one end by the bracket 3S and at. the other end byextensions 51. from the bracket 85. It Will be understood that the underrun ot' the chain 40 is above thesheet path and that the gripper iau'sin opening, therefore, cross the sheet path.

In order to prevent the jaws 43 from pressing upon and possibly tearingthe sheet, means l.n'iay be provided for permitting the sheet te bendaway from the grippers and tor lifting the sheet so`that its The-cutawayplace iin this table filled- V66 by' a leaf the front end of which is.l

seizure by the. grippers. is insured. While these means may be varied,in the particular construction illustrated, the sheet, after leavingth\A abutment roll, is received on a table or platform (see Fig. 3)which is cnt away about midw r of' its forward edge.

This construction enables the formed by a tongue 54 flanked by recesseswhich are in the path ot the gripper jaws 43 as they swing downward.This leaf' is hinged at 5G to the table 52, and suitable Ameans isprovided for rocking the leaf downunder side (see Figs. 4 and 5) tivobrackets 57 to support a short shaft 58. This shaft is provided with anarm 59 to which is secured an'arm 60 extending from a hub 61 looselymounted on a cross-shaft G2. This hub G1 has extending from it an arm 63to which is secured a spring rod construction 6st of ordinary type whichis operated from a cam G5, suitably mounted in the machine. In theoperation of this part of the mechanism (see Figs. 4, 7 and 8) as thesheet advances across the table 52 and as the ripper is opening, the eat53 is rocked downvard. At the time the gripper is fully opened, theparts occupy the position shown in Fig. 4. Assoon as the grippers arebeyond the edge ot the sheet, the leaf is lifted, as shown in Fig. 8,thus bringn'ng the edge of the sheet into position Where its seizure bythe gripper is insured.

Certain novel features of constructionl claimed is not to be confined tothc particular construction herein shown and described,

as changes and variations may be made therein without depart-ing fromthe claimed invention.

What is claimed is 1. A sheet delivery mechanism including incombination means for advancing a sheet fiat. said means including,rdevices for holding the original edges ot the sheet, means for dividingthe sheet, and sheet forwarding means acting to positively seize thesheet and operating on the sheet on each side next the cut termed bythe, dividing means.

2. A sheet delivery mechanism including in combination means foradvancing a sheet flat, said means including grippers operating on'tlieoriginal edges otthc sheet, a slitter forV dividing the sheet, and sheetforwarding grippers operating on the sheet'on cach side of the cutformed by the slitter.

3. A sheet delivery mechanism including in combination a pair oftraveling flexible gripper carriers one on each side ot' the sheet path,gripper.; on the carriers, av slitting mechanism for dividing the sheet,and grippers operating on thel .sheet on each side ot the out formed bythe. slitting mechanism.
